TITLE 326 AIR POLLUTION CONTROL DIVISION

The Indiana Department of Environmental Management (IDEM) is soliciting public comment on amendments to rules at 326 IAC 7-4.1-16 concerning updates for sulfur dioxide monitoring and fuel sampling processes for Safety-Kleen Oil Recovery Company. IDEM seeks comment on the affected citations listed and any other provisions of Title 326 that may be affected by this rulemaking.

The Clean Air Act (CAA) requires that the United States Environmental Protection Agency (U.S. EPA) set National Ambient Air Quality Standards (NAAQS) for pollutants that cause or contribute to air pollution, which may reasonably be anticipated to endanger public health and welfare. U.S. EPA has set NAAQS for 6 criteria pollutants, one of which being sulfur dioxide (SO₂).

Safety-Kleen Oil Recovery Company (Safety-Kleen), Source Identification Number 00301, owns and operates an oil re-refinery in Lake County, Indiana. Safety-Kleen is subject to SO₂ limits in 326 IAC 7-4.1-16. Safety-Kleen chose to comply with the use of off-gas analysis and fuel sampling for process heaters H-201, H-401, and H-406 with the compliance deadline of December 31, 2005. The method of SO₂ monitoring compliance at 326 IAC 7-4.1-16(5)(A) uses off-gas stream for process heaters H-201, H-401, and H-406 and includes fuel sampling and analysis for the sulfur content of the fuel in each fuel tank. The fuel sampling occurs after the fuel in the tank has been mixed to ensure consistent composition and must be done prior to the first fuel burning and prior to burning the fuel when additional fuel has been added to the tank. Safety-Kleen agreed to maintain records sufficient to demonstrate compliance for at least 3 years and submit any excess emissions reports to IDEM within 30 days after the end of each calendar quarter. IDEM has determined that this method (specifically off-gas analyzers) is dated and maintenance intensive, making it a nonviable option of SO₂ monitoring for complying with the state and federal emission regulations. An enforcement action was issued due to violations of the SO₂ emission limits; therefore, Safety-Kleen plans to update their SO₂ monitoring method using continuous emission monitor systems (CEMS) for process heaters H-201 and H-401. Safety-Kleen is planning to install CEMS for stacks H-201 and H-401 while continuing to use off-gas stream monitoring for Process Heater H-406. IDEM is updating the rule language to reflect the SO₂ monitoring method being requested by Safety-Kleen so that the source is in compliance with the pending enforcement action. IDEM will replace 326 IAC 7-4.1-16(5) with new language to address the monitoring needs for the source.

Safety-Kleen provided IDEM with 5 years of historical data from process heater H-406 to show that this unit is well below the current emission limit of 8 pounds per hour (equivalent to 192 pounds per day) for SO₂, averaging 0.34 pounds per day. This rulemaking will enable Safety-Kleen to install CEMS for process heater stacks H-201 and H-401 while continuing to use annual sulfur content monitoring for H-406. IDEM is not proposing to remove compliance demonstration requirements for other units at this source. This rulemaking will be submitted to U.S. EPA as a state implementation plan (SIP) revision for their approval.

IDEM seeks comment on the affected citations listed, including suggestions for specific language, any other provisions of Title 326 that may be affected by this rulemaking, and alternative ways to achieve the purpose of the rulemaking.

The Lake County SO₂ emission limitations at 326 IAC 7-4.1-16 are approved at the federal level into Indiana's SIP. Any revision to the SIP needs to be approved by U.S. EPA. IDEM will base revisions to 326 IAC 7-4.1-16 on alternative requirements requested by Safety-Kleen while maintaining SO₂ emissions that are within current federal and state standards.

Potential Fiscal Impact of Alternative 1. This alternative has a potentially significant negative fiscal impact on the source; however, Safety-Kleen has requested that IDEM revise the rules at 326 IAC 7-4.1-16 to change the SO₂ monitoring requirements for process heater stacks H-201 and H-401 located in Lake County, Indiana in order to comply with the enforcement action issued by the department. Safety-Kleen is planning to install CEMS for process heaters H-201 and H-401 to comply with the state and federal SO₂ regulations. Installing two SO₂ CEMS has an associated cost of $250,000 with an annual cost of $50,000 for maintenance and operation per unit which comes to a total approximate cost of $600,000. Safety-Kleen will need to install CEMS to both process heater stacks to comply with the SO₂ standards and the enforcement action.

Potential Fiscal Impact of Alternative 2. This alternative will not have a fiscal impact on the source. If this rulemaking does not occur, the conflict between monitoring requirements in the agreed order and the current rule will not be addressed.
